Over time, as devs get more experience, they have seen countless fads come and go. Some worked, some screwed things up, etc. - NONE were the silver bullet / savior that they were touted to be by adherents. So they learn a default "no" or "slowly" response to "we need to do this <buzzword> ASAP" from management who only see $$$. I mean AI companies are telling management that devs will resist AI because "it's so good it will let you replace them", so management is getting their views reinforced by devs saying it's a bad idea.
